El estudio investigo el impacto de la edad (E) y variedad (V) en varias características planta, incluida altura planta (AP) centímetros, biomasa del forraje (FB) kilogramos materia seca por hectárea, peso tallo (PT), número hojas. (LH), área foliar (LA), relación hoja-tallo (LSR) composición química tres especies gramíneas: Axonopus micay, scoparius Melinis minutiflora. Los pastos se cosecharon cinco estados diferentes madurez (30, 45, 60, 75 90 días). Se empleó un diseño bloques completos...
Plants" natural defense mechanisms against herbivorous arthropods include the emission of volatile organic compounds (VOC).Nowadays field observations about plant-insect interactions are better understood thanks to increasingly scientific investigations over recent decades.There now more precise data molecules, action modes and physiological genetic bases these plant mechanisms.VOC present an important potential for crop protection pesticide use reduction.In review, we focus on latest...
The species of Scolytinae subfamily have a worldwide distribution, and are found mainly in the Neo-tropic regions. They usually dominate communities wood borer insects. aim present study was to determine diversity among associated with balsa, teak, rubber gamhar plantations located humid tropical zone Ecuadorian littoral. In each plantation seven flight interception traps containing an ethanol / gel mixture were installed, collection frequency 15 days for three months dry period. A total...
La era Omica ha abierto una nueva ventana a la biología. genómica y transcriptómica son dos campos conocidos, con los cuales, selección el mejoramiento de plantas se estudian mayor facilidad precisión. Proporcionan información útil sobre genes, las transcripciones, sus funciones sirven como datos primordiales para otros enfoques posteriores. Los genomas referencia varias han sido secuenciados, están disponibles, facilitando así acceso ómica indispensable llevar cabo estudios basados en...
Three Gossypium species have been used to breed cotton as they vary in their fiber production and resistance stresses. Transcription factors (TFs) mostly are present different copies or isoforms by which conduct regulation. Their copy number can determine organism behavior a cue. Simple sequence repeats (SSRs) one of the most informative versatile molecular markers. three were compared silico. Seventy eight percent TFs common between species. Single for each 6057 TF. hirsutum G. raimondii...
The variability of climatic conditions throughout the year and physiological maturity plant material can have effects on nutritional value plants productive performance animals. aim was to determine effect three tropical forage species (Tithonia diversifolia, Erythrina poeppigiana Cratylia argentea) harvested at four cutting ages (30, 45, 60 75 days), during dry rainy seasons in vitro gas production, rumen pH, volatile fatty acids (VFA) CH4 production. A completely randomized design a...

Cotton is a resilient and multipurpose crop, meeting major of the world’s textile needs while also yielding byproducts like edible oil animal feed. Starch plays crucial role in cotton fabric production. It enhances strength by forming protective film around fibers, making them more resistant to wear tear. BES1 (brassinosteroid insensitive 1) key regulator brassinosteroid signaling. controls thousands target genes involved development processes. Interestingly, two β-amylase proteins (BAM7...
El conocimiento sobre la biologÃa del polen es fundamental para planificación de cruzamientos controlados en programas conservación y mejoramiento genético especies vegetales. Esta investigación tuvo como objetivos determinar el medio idóneo germinación in vitro evaluar efecto temperatura secado viabilidad almacenado Ochroma pyramidale. se obtuvo flores colectadas previo a antesis. cultivo adecuado realizar determinó probando modificaciones propuesto por Brewbaker Kwak (BK). realizó...
Cacao and coffee are two tropical crops with an essential annual turnover.Alkaloid products like caffeine theobromine show that these species share related pathways in alkaloid metabolism.Genomic proteins of three species, including Coffea arabica, C. canephora eugenioides, cacao Theobroma cacao, Herrania umbratica, were compared analyzed based on protein clustering GO terminology.A comparison all five showed orthologous involved stress, disease response, biosynthesis, regulation...
The fruit fly (Diptera: Tephritoidea) is a pest with high phytosanitary impacts and economic importance worldwide. In Ecuador, causes significant losses affecting more than 260 different types. This study was aimed to estimate capture effectiveness in orange tree regulated by volatile alimentary attractants propose an alternative biological control. experimental unit constituted Multilure trap (McPhail plastic wet version) for each vegetable attractant. Five one control were compared....
Transcription factors (TF) are the elements, which regulate gene expression. Regulatory function of TFs play an important role in plant biological processes and mechanisms. They may interconnect with other transcription or functional genes to modulate their expression response internal/external factor like life cycle stage, growth, development stress. Arabidopsis is well-known most used model organism. three species including A. halleri, lyrata thaliana, were compared. basic/helix-loop-helix...
The present research was aimed to evaluate the effectiveness of attractants placed in craft traps reduce bit population (Hypothenemus hampei). Three different mixtures and control were used (4 treatments, which represent frequently by Amazonian coffee growers), arranged a completely random blocks design. variable number adult drill analyzed, as well most economical effective treatment capture bit. data processed means variance analysis determine differences between Tukey media multiple...
Oyster mushroom (Pleurotus ostreatus (Jacq. ex Fr.) P.Kumm. (1871) is a rich food source. It cultivated on compost and plant waste material. Choosing adequate substrate essential for oyster production as the can change in terms of mass metabolite composition. The different medium substrates including T1 (PDA, potato-dextrose-agar), T2 (CCA: PDA + Cocoa Shell), T3 (APR: African Palm Rachis), T4 (BP: Banana Peel), T5 (CCO: Coconut Peel) were used. Based mycelial diameter, CCO treatment was...
Peganum harmala is a valuable wild plant that grows and survives under adverse conditions produces pharmaceutical alkaloid metabolites. Using different assemblers to develop transcriptome improves the quality of assembled transcriptome. In this study, concrete accurate method for detecting stress-responsive transcripts by comparing stress-related gene ontology (GO) terms public domains was designed. An integrated P. including 42 656 coding sequences created merging de novo transcriptomes....
La investigación se realizó en dos tipos de finca (orgánica y convencional) tuvo como objetivo determinar la eficiencia enmiendas floables sólidas corrección pH el cultivo palma aceitera. Para ello emplearon tres enmiendas, una sólida. Los lotes fueron divididos parcelas 9x27 m que ocuparon 8 plantas cada uno, con cuatro tratamientos repeticiones. Se empleó un diseño divididas (DPD) completamente al azar (DCA). resultados sometidos a prueba Tukey 95% probabilidad. El mejor tratamiento para...
